The Interplay Between Observation and Theory and Instruments

Hobble discovered the expansion of the universe, and he thought it was an expansion at a constant rate. The distance out to which habel had measured the expansion, those three solutions actually look very close. They sit on top of each other. Well, we'llwe have to go further back in time now to start to see the divergence of the three solutions. We obviously are dictated by the foundational physics and mathematics that describe phenomena. But it involves leaps of imagination, always because of the kinds of scales we deal with rit they are really out of the realm of common familiarity.
